Specification of Letters Patent` Patented Sept. 14, 1920.

`Applii'zation filed July 16, 1919. Serial No. 311,358.

` ing at Grand Rapids, inthe county of Kent and State of Michigan, haveinvented cer tain n ew and useful Improvements 1n Humidiiers; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others Skilled in the art to whichit appertains to make and use the same.

This invention relates to humidiiiers and is particularly concernedwitha humidifier which may be very quickly and easily applied toradiators of steam or hot 'water heating plants and which from itsconstruction is capable of giving to the air of the room heated by saidradiator the requisite and necessary degree of humidity. It is an objectand purpose of the invention to make a humidilier which contains amember for passing over the upper end of a radiator and which isequipped with means for inclosing a space above the radiator in which`air is heated and circulated, the same passing over a pan containingwater whereby the heated air absorbs water 4vapor and is deliveredthrough an opening in said member into the room, supplying the air ofthe. room with water vapor and raising the relative degree of humidity.A further object of the ,invention is to so construct the device that itcan be made at small cost and can be applied to radiators for usewithout employment ot' skilled` labor land in fact without the use oftools in any way, the humidiiier being added without change to theradiator practically instantaneously.

For annnderstanding of the invention and the construction which attainsthese results als well as lmany others not specically stated at thispoint, reference may be had to the following description taken inconnection with the accompanying drawing, in which,

Figure l is a perspective view of the humidifier hood.

Fig. 2 is a partial vertical section and end elevation, the sectionbeing taken through the humidifier transversely thereof.

Fig. 3 is a longitudinal vertical section through the humidifier, theradiator to which it is applied being shown in side elevation.

4water heating installations.

c Like reference characters refer to like parts n1 the d1iferent figuresof the drawing". In construction, an inclosing hood having Y a frontside l and a .rear side .2 spaced apart are connected by an integralcurved top 3 and has ends et, all made, preferablyI from sheet metal.The under side is open so that the hood may be passed over the upper endof the usual radiator used in steam or hot At the upper portion of theiront sidel and practically at the point where it joins with the curvedtop 3 a central opening 5 is made and the metalis pressed from the hoodso as to 'fpi'm a downwardly and outwardly inclined top or cover 6over'the opening, the ends between the said cover and the remainder of.

the hood being closed by end pieces 7.

A supporting bar ot metal isflxed within the hood and disposedlengthwise thereof, it including a central section 8 which lies,directly against the under side ot the top 3 and from which, at eachend, sections 9 are bent downwardly for a distance and thencehorizontally, as indicated at l0, until 'the ends i ot'- the hood arereached, being permanently connected to said ends 4 by rivets` or othersuitable permanent connections..

' The hood is adapted to be passed over the upper end of, a'radiator 11until the horizontal sections i0 are brought to rest against therupper-Vend of the radiator. This leaves a considerable space between the upperend of theradiator and the hood as is evidentv Before placing the hoodlover the radiator a saddle comprising anupper horizontal plate 12 withdepending front and rear sides l13 is placed over the radiator at aboutits middle point between its ends, this making a support for a shallowpan li which may be inserted .through the opening 5 and placedon thesaddle. i filled with water and is practically in direct contact withthe radiator from which itrelhis pan is ajlapted to be the heated airwithin the hood passes over the pan and water therein, absorbing thewater vapor andcarrying it with the air out through the opening 5. Thetop 6 over the opening has the function of directing the air downwardlyout of the hood and causing it to pass over the water, thus mak ing theabsorption of yvapor more sure and rapid.

The huniidilier has been in extensive practical service and has proventhoroughly efiicient. The air heated within the inclosure has a tendencyto escape from the hood and carry the vapor with it, new cold air comingup from beneath into the hood. There is a continuous circulation and theheated air is directed downwardly from the hood and thus circulatesthroughout the entire space in the room, carrying its supply of vapor.The vapor rises readily from the shallow pan 14: and is quickly absorbedAby lthe heated air. The construction is very economical to manufacture,and has proven exceptionally efiicient in tests and service.

I claim:l

l. ln combination, a hood having spaced front and back sides andvertical ends, an integral ronnecting top joining the front,

back and ends, said' front side having an opening therein with metalpressed :from the hood over said opening in a downward and outwardincline, a bar attached to the upper side of the hood at its middleportion and formed with downwardly bent sections for a distance andthenterminating in horizontal sections exitending` `to the ends of thehood, and meansr connecting the bar to the hood at its ends and at itsmiddle portion, substantially as and for the purposes described.

2. In combination, a hood having spaced front and back sides andvertical ends, an integral connecting top joining the front, back andends, said front side having an opening therein with metal pressed fromthe hood over said opening in a downward and outward incline, and meansconnected to and within the hood and extending downwardly from the topof the hood near each end thereof to serve as a support for the hoodwhen placed over a radiator, the intermediate portion of the hood beingunobstructed, substantially as described.

In testimony whereoic I aliix my signature.
